| Quantitative evaluation of matching methods and validity
measures for stereo vision |
 |
| |
| Multimedia extension #5: Application of constraints
to remove invalid matches |
| |
| All disparity maps are computed using the rank
transform with a 5 x 5 window. In order for a pixel to be valid it must
pass: |
| |
| • pass the left-right consistency check |
| • the local anomoly test |
| • local texture test |
| • match score test |
| • ambiguity score test |
